FDG Group Limited

Professional and amazing service from FDG. Our heat pump is a dream and we are looking forward to having our solar panels fitted. Thanks again!

Toasty warm with our air source heat pump this winter. Thank you to Jon, the ace engineer who resolved a misbehaving radiator with a few words of advice - by text. 👍

We are happy with our ecoflow battery, which was installed very quickly. Our WiFi signal didn't reach but Chris was really helpful in getting this sorted. The battery seems good and the app is intuitive. We are looking forward to getting the documentation so that we can switch tariffs, but hopefully that will be a efficient as the installation.

Beware of using this company. We had issues with the installation of our PV system back in 2019 which they only rectified when forced to do so by HIES, which they were still a member of at the time. In summer 2025 we contacted them about a fault in the battery and after chasing them up they sent an engineer, but only after we had paid an upfront cost of £399.99. The engineer announced that the battery could not be fixed, and spent the remainder of his time trying to push us into paying thousands of pounds for another battery. He claimed to have contacted Solax on our behalf and reported back that our battery was not covered under guarantee. In the next few weeks we contacted Solax ourselves and received very helpful advice and telephone support in setting up a dongle to monitor the battery. They were then able to replace the battery under guarantee, and we found an honest solar engineer to install it. Don’t expect this sort of service from FDG!

FDG have just replaced my older battery with a new EcoFlow smart battery. They were on time, efficient, and did a good job as always. I have used this company for the last 6 years.

An update to the previous review, now that we've had the heating on for a while. Initially, I wanted to say a big thank you to Steve, Jon and the rest of the team, for their expertise and the professional fitting. We have had FDG fit solar panels, inverter, batteries, car charger and a heatpump to our 1960’s house. They have also changed and added some radiators. All the work was done professionally and everything was left tidy with all rubbish taken away. The heat pump is keeping the temperature at a constant cosy level, and keeps us with a good supply of hot water. The solar panels have kept the battery topped up all spring and summer, and we've been paid over £400 for the excess we have exported back to the grid. Now into Autumn we can charge the 10kW battery overnight at 6.6p per kW and most days that and the electricity from the solar panels is enough to heat and run the house. With the EV charger, we can schedule it to charge the car for the same 6.6p per kW which means that the cost to fully charge the car is less than £5, which is good for 300 miles (so the car claims!).

Excellent work, the panels look amazing and the work was completed efficiently without disturbance. They even fixed the broken roof tiles they found that we were unaware of!. Chris and Ian were especially helpful. Would recommend
